In addition to SCI1, the H8/3937 Series and H8/3937R Series have two serial communication
interfaces, SCI31 and SCI32, with identical functions. In this manual, the generic term SCI3 is
used to refer to both of these SCIs.
Serial communication interface 3 (SCI3) can carry out serial data communication in either
asynchronous or synchronous mode. It is also provided with a multiprocessor communication
function that enables serial data to be transferred among processors.

Choice of asynchronous or synchronous mode for serial data communication
Asynchronous mode
Serial data communication is performed asynchronously, with synchronization provided
character by character. In this mode, serial data can be exchanged with standard
asynchronous communication LSIs such as a Universal Asynchronous
Receiver/Transmitter (UART) or Asynchronous Communication Interface Adapter
(ACIA). A multiprocessor communication function is also provided, enabling serial data
communication among processors.
There is a choice of 16 data transfer formats.
